Beschreibung
Zusammenfassung:	The invention relates to a method for enhancing ignition success rate of a gasification furnace start burner, which is a method for enhancing ignition success rate of a start burner in a coal powder pressure gasification device. The method comprises the following steps: if the flame detection system detects a normal flame signal in the ignition stage, shutting down the ignition rod, opening a first cut-off valve of the start oxygen path, and starting the ignition rod again; and if the flame detection system detects an abnormal flame signal, continuing ignition without shutting down the ignition rod. The working time node of the electric ignition rod in the ignition start process is controlled to enhance the ignition success rate of the start burner.
